- "This place, what happened here?"
"For about seventy years after World War II, nothing; no one even knew it was here. Then a couple years back, a brave agent named Billy Koenig gave his life getting me the location. It's taken all that time just to get it operational again."
- ―Jemma Simmons and Jeffrey Mace
The Playground is a virtual recreation of the real-world S.H.I.E.L.D. headquarters of the same name that serves as the headquarters for the Resistance inside the Framework.
In order to showcase the abilities of the Framework, Leo Fitz and Jemma Simmons rendered a version of the Playground, consisting solely of the training room, for Phil Coulson and Daisy Johnson to spar in.
The Playground within the Framework rendered by Aida and Holden Radcliffe was in a poor state of disrepair. Jeffrey Mace, Inhuman leader of the Resistance, learned of its existence from a loyal S.H.I.E.L.D. agent called Billy Koenig, who sacrificed his life in revealing its whereabouts to Mace. It was abandoned for seventy years and no one knew of its existence. It took the Resistance several years to get the facility operational.
During the early days of the Resistance using the Playground as a base, many agents died and their names were carved into a brick wall within the base as a Wall of Valor. The facility is also a sanctuary for allies, those of Inhuman potential, and their families.

- As the set for the real-life Playground as it exists currently was reused as-is for its appearance within the Framework, a number of visual changes to the base that occurred in real-life between Season Two and Season Three have been disregarded within the Framework. This is despite the fact that in the Framework, the base stood abandoned for approximately 70 years and that the Resistance had limited funds and resources to get the base barely operational, much less upgrade its facilities.
- The hangar had a different floorplan (including different markings on the ground) and the doors were originally smaller as the hangar did not need to accommodate an aircraft as large as Zephyr One.
